① Raw Materials: Ethylene oxide (EO) prices in East China reached 9,700 RMB/ton, while domestic ethylene prices fell to 9,000 RMB/ton.
② Demand: The market is characterized by a strong wait-and-see attitude, with low willingness among downstream buyers to enter the market for procurement.

Today, domestic polycarboxylate superplasticizer monomer prices continued their downward trend. The raw material ethylene oxide (EO) market maintained steady trading activity with firm price movements. However, today, producers in East China saw an increase in available inventory, leading to softer offer prices. Major external buyers of styrene are facing sustained losses, resulting in purchasing primarily at lower price points. Combined with bearish expectations from industry participants regarding future trends, today's transactions were mainly driven by rigid demand. With insufficient cost support from the EO market, monomer producers offered discounts to facilitate sales. Downstream replenishment enthusiasm remained low, and trading sentiment was subdued. In summary, the price of EPEG in the key East China market is expected to range between 10,300–10,600 RMB/ton on the next working day.
Today, the capacity utilization rate of the polycarboxylate superplasticizer monomer industry stood at 24.21%, representing a month-on-month decline. The gross margin for HPEG (a type of polycarboxylate superplasticizer monomer) was -79 RMB/ton.
On the next working day, domestic polycarboxylate superplasticizer monomer prices may undergo slight weak adjustments. Key raw material ethylene oxide prices may remain stable as the market adopts a wait-and-see approach. Spot supply of EO may see a certain increase, while downstream industries will continue to purchase based on rigid demand. Available ethylene inventory has increased, prompting producers to actively offer discounts to clear stockpiles, suggesting a potential narrow downside movement in prices; however, cost-side support remains limited. Within the monomer market, low-priced supplies have increased, with industry participants maintaining a bearish outlook. Downstream procurement sentiment is cautious, market trading atmosphere is cold, and transactions are negotiated based on volume. In summary, the price of EPEG in the key East China market is projected to be around 10,300–10,600 RMB/ton.
① Ethylene Oxide (Raw Material): EO prices may maintain a temporarily stable status. On the supply side, rising prices for related product monoethylene glycol (MEG) have strengthened the incentive to shift production towards MEG via co-production facilities, meaning there is no significant increase in EO supply yet, with some regional tightness in availability. On the demand side, major downstream industries have limited absorption capacity for EO, focusing primarily on rigid demand. Post-holiday market sentiment remains heavily weighted towards wait-and-see attitudes. On the cost side, domestic ethylene prices have pulled back, with the market relying mainly on pre-sales. Downstream derivative enterprises stocked up during the holiday period, limiting new order transactions. Overall, there is certain support on the supply side, and EO prices are likely to remain temporarily stable in the short term, requiring continued monitoring of upstream and downstream dynamics.
